    摘要: Embodiments of a lightweight, high temperature airborne valve are provided. In one embodiment, the airborne vale includes a valve element and a flowbody. The flowbody is formed at least partially from a titanium aluminide alloy and has a flow passage therethrough in which the valve element is movably mounted. Embodiments of a method for producing such a lightweight, high temperature airborne valve are also provided. In one embodiment, the method includes the steps of forming a lightweight flowbody at least partially from a titanium aluminide alloy, hot isostatically pressing the lightweight flowbody, and machining the lightweight flowbody to desired dimensions.

    摘要: A silicon on sapphire (SOS) semiconductor structure may be processed to improve the electrical characteristics of a silicon film on a sapphire substrate by silicon-regrowth (SRG) techniques using oxidation to remove silicon from the outward surface of the silicon film. An epitaxial film on a sapphire substrate is implanted with silicon to amorphize the silicon film except for a thin seed layer on the outward surface of the silicon film. The silicon is recrystallized inwards using the seed layer as a seed for crystallization. The silicon film is oxidized to produce an oxide layer on the outward surface of the silicon film, the SOS structure may be heated to densify the oxide layer, and the oxide layer is etched away. This produces a silicon film with a reduced p-type electrical activity and improved crystalline quality surface so that the channel mobility is improved for semiconductor devices fabricated in the silicon film.
